How to get rid of big roots?

[Samnet]

Hi all,

Need advice how to get rid of these roots.

Moved in to a new house and these roots are all over the entrance on a rock. However, they have gone under the entrance pathway and might be under building as well.

Really worried about the damage they have made.

How can I get rid of them?

Thanks 

Sam

thanks @MitchellMc 

I just bought these 2

Do I need to get Zero as well? Or these 2 do the job?

[MitchellMc]

They'll do the job @Samnet. Roundup is the same as Zero.
